An embodiment of the invention is illustrated in the accompanyingdrawings, in which Figure 1 is a side elevation of an earth boringmachine.

Fig. 2 is a top plan thereof.

Fig. 3 is a rear elevation.

Fig. 4 is a section on the line 4 4 of 5 is a section on the line 5-5-of Fig. 7 is a section on the line 7-7 of Fig. 2.

. he earth boring machine has a frame 1()A and wheels 11 forming thechassis of a vehicle. Chassis frame 10 vsupports aturntable 14. Uponturntable 14 is mounted the operating motor, auger tower andtransmission and control mechanism whereby the motor supplies the powerfor producing the desired operations of the boring, auger and theoperations thereof are controlled.

Rigidly secured to chassis frame 10 is a gear wheel 12, through whichthe turntable is rotated, and a circular track 13, upon which theturntable is mounted.

The turntable is pivoted to chassis frame 10 by a stud or shaft 15 whichis rigidly secured to the frame and passes axially through gear wheel12. vThe frame of the turntable is composed of two side bars 150, endmember 16 and transverse stays 17. These members may be made fromchannel iron. Secured to the bottom of the frame is an annular turntablesupport or track 18. Support 18 is formed of parallel facing channelbars to which are secured a number of journaled rollers 19.. Rollers 19rest upon track 13 and convey thereto the weight of the turntable andthe apparatus carried thereby and upon these rollers the turntable maybe rotated.

Mounted on one end of turntable 14 is a motor 20, such as a gasoleneengine. Engine 20 has a shaft 21 which is connected to a mainshaft 22 ofthe transmission mech` anism by a sprocket wheel andchain connection 23.Main shaft 22 is located longitudinally intermediate the ends of-turntable 14 and extends entirely across the same.

From main shaft 22 power is taken for rotating the turntable to positionthe auger relative to the work, for rotating the auger to effect theboring operation, pfor-raislng and lowering the auger and for tiltingthe auger to produce inclined holes or move the auger to carrying andoperating positions, ete.

Ro tat'lag turntable.

reverse direction through an intermediate shaft 26. Rotatably mountedupon shaft .25 is a sleeve 27 to 'which is rigidly connected the cu of aclutch 28 and a sprocket wheel 29. n endless chain 30 interconnectssprocket wheel 29 and a sprocket wheel 31 keyed 'to shaft 22. The cone32 of clutch 28 is mounted to slide upon and rotate shaft 25. ,Cone 32is moved along shaft 25 into and out of driving position by a lever 33,which is operated through a link 34 and a rod 35 by an operators lever36.

Shaft 26 is provided with a sleeve 37 rotatably mounted thereon. Sleeve37 has rigidly secured thereto the cup of a clutch 38 and a sprocketwheel 39. Sprocket wheel 39 is interconnected by an endless chain 40with a sprocket wheel 41. Sprocket wheel 41 is keyed to main shaft 22.The cone 42 of 4clutch 38 is adapted to slide upon and rotate shaft 26.Cone 42 is moved into and out of driving position by a lever 43 which issecured to link 34 by a pivot 44. Clutches 28 and 38 are thereforesimultaneously operated by operators lever 36. The relation of theclutches is such that both may be in non-driving position at the sametime, when the turntable is to be held relatively stationary and one orthe other, but never both simultaneously may be in driving position torotate the turntable in the desired direction.

Shaft 25 drives shaft 24 through meshing gear wheels 45 and 46, keyed tothe respective shafts. Shaft 26 drives shaft 24 through sprocket wheels47 and 49, keyed to the respective shafts and interconnected by anendless chain 48. Shaft 24 is thus driven in one direction by shaft 26and in the opposite direction by shaft 25.

A beveled gear wheel 50 is keyed to shaft 24. Gear wheel 50 meshes witha beveled gear wheel 51 keyed to a shaft 52 which also carries a pinion53 meshin with gear wheel 12.' Consequently when s aft 24 is drivenineither direction pinion 53 rotates upon and about the stationary gearwheel 12 and the turntable is accordingly rotated.

If, for example, the turntable is to be turned to the right, operatorslever 36 is moved to throw in clutch 28. The turn table is then rotatedby the engine through chain 23, shaft 22, chain 3,0, clutch 28, gearwheels 45 and 46, shaft 24, ear wheels 50 and 51, pinion 53 and gear weel 1.2.

When the turntable is to be stopped lever 36 is moved to mid-positionwherein both clutches 28 and 38 are thrown out of driving position. y

To reverse the direction-of movement of the turntable, operators lever36 is moved to the opposite position. Thereupon clutch 38 is thrown inand the engine rotates the turntable through chain 23, shaft 22, chain`40, clutch 38, chain 48, shaft 24, gear wheels 50 and 51, pinion 53 andgear wheel 12.

The turntable may therefore berotated in either direction upon themanipulation of a single lever readily accessible tomthe operator. T herelation of the clutches pro-vides a positive safety arrangement forpreventing both clutches from being thrown in simultaneously which mightresult in broken gears, sprocket wheels, chains, shafts, or other partsof the structure. The proper operation of the turntable is thus insuredand theauger may be readily and quickly positioned above the work.

Rotating auger.

The auger is rotated always in the same direction by the engine and theloperation may be started and stopped by the manipulation of a singlelever.

Shaft 22 has rotatably mounted thereon a sprocket wheel 80. Sprocketwhel 80 is rigidly secured to the cup 81 of a clutch 82. Cup 81coperates with a clutch cone 83 which is adapted to slide longitudinallyupon and be rotated by shaft 22. A lever 84 is Asecured to cone 83 andacts to force the cone into and out of engagement with cup 81. Lever 84is actuated through a rod 85 by an operators lever 86.

An endless chain 87 interconnects sprocket wheel 80 and a sprocket wheel88, which is (See particularly Figs.

located in a gear box carried by thel lower end of the auger tower.

An auger or boring tool 104 is carried on the end of an auger shaft 103.Shaft 103, which has a square cross section throughout the greaterportion of its length, passes through a square opening in a sleeve or'bushing 110 of gear wheel 109. Shaft 103 is adapted to slide throughthe opening in sleeve and gear wheel 109, Abut is rotated `when gearwheel 109 revolves.

Raising amd lowering wager.,

Theauger is lowered and raised or driven to and from the work by theengine and its up and down movement is independent of the rotation sothat these operations may be independently varied to best suit theconditions of the work.

Keyed to shaft 22 is a bevel gear wheel 54. Gear wheel 54 meshes with abevel gear wheel 55 keyed to the end of a shaft 56 journaled in abearing 57. Surrounding shaft 56 is a sleeve 160. Sleeve 160 isfeathered to shaft 56 so as to be adapted to slide upon but be rotatedthereby. Sleeve 160 is journaled in a collar 161 movably carried in athrust bearing 58 and thus supports one end 0f shaft 56. Rigidly mountedupon sleeve 160 are a pair of facing bevel gear wheels 59. Gear wheels59 are adapted to engage either of two facing bevel gear wheels 60 and61. Collar 161 has a pin 162 extending through a spiraled slot 163 inbearing 58 and carries a lever 164. When lever 164 is rotated collar 161is turned and the coperating pin and s-lot move sleeve 160 and gearwheel 59 to the right or left, as viewed from Figs. 1 and 2, dependingupon the direction of rotation. v

The position of gear wheels 59 relative to gear wheels 60 and 61 iscontrolled by a lever 77 which moves lever 164 and is interconnected bya rod 78 with an operators lever 7 9. i

Gear wheel 61 is keyed to the end of a shaft 63. A sprocket wheel 72 isrotatably journaled on shaft 63 and carries a cup 73 of a clutch 74.Clutch 74 has a cone 75 keyed t0 slide upon and rotate with shaft 63;Clutch 74 is thrown into and out of driving connection by a lever 76interconnected by a rod 70 with an operators lever 71.

Sprocket wheel 72 is interconnected by an endless chain 90 with asprocket wheel 91 carried by a sleeve 92 which is journaled upon shaft89. Sleeve 92 has a sprocket wheel 93 rigidly secured thereto. Sprocketwheel 93 is interconnected with a sprocket wheel 94 by an endless chain95. Sprocket wheel 94 is keyed to a shaft 96 journaled in bearingscarried by the auger tower.

The auger tower comprises four posts 100 of angle iron, rigidly securedat their bottoms to a gear box 105. Gear box 105 is journaled onopposite sides upon the turntable by shaft 89-and a'trunnion 111, whichhave suitable bearings supported by the turntable framework as shown inFig. 6. Posts 100 carry a pair of longitudinally extending guides 101which provide ways for the opposite sides of a slidin cross-head 102.Head 102 has journaled t erein a circular cross sectioned portion ofauger shaft 103, whereby, when the head is moved up and down in thetower, the auger shaft and auger are raised and lowered. The head andits guides brace the upper end of the auger shaftv so that the same issecurely retained 1n proper position within the tower and is protectedagainst objectionable deflection.

Head 102 has a lug or clamp to which is secured lan endless chain 112.Chain 112 passes over a sprocket wheel 113 journaled at or near the topof the tower and a sprocket wheel 114 keyed to shaft 96. Thus- Wheel 72,chain 90, sprocket wheel 91, sleeve 92, sprocket wheel 93, chain 95,sprocket wheel 94, shaft 96 and sprocket wheel 114 and chain 112. y

To move the auger in the reverse direction, operators lever 79 is thrownto the reverse position, whereupon the right hand gear wheel 59 engagesgearwheel 61 (see The direction of rotation of shaft 63 is thus reversedand consequently the movement of the auger shaft and auger 1s reversed.

Tilting auger' tower.

The auger is tilted or inclined by the engine and the tilting movementmay be controlled by a single lever.

Gear wheel 60 is keyed to a shaft 62 which has journaled thereon asleeve carrying a ear wheel 64v and a cup 65 of a clutch 66. lutch 66hasa cone 67 adapted to slide upon but rotate with shaft 62. Cone 67 isprovided with a lever 68 which is connected to rod by a link 69.Consequently when operators lever 71 is actuated, it movesI cone 67 intoan out of driving connectionV with cup 65. The relation of clutches 74and 66 and their operating connections are such that when one clutch ismoved to driving position the other clutch is simultaneously moved outof driving position. Thus it is impossible to raise or lower the augerwhile it is being tilted and vice versa.

Gear-wheel 64 meshes with a pinion 115 towhich is secured a sprocketwheel 116. An endless chain 117 interconnects sprocket wheel 116 and asprocket wheel 118. Sprocket wheel 118 is keyed to a shaft 119 whichalso has keyed thereto a bevel pinion 120. Pinion 120 meshes with abevel pinion 121, keyed to the end of a short vertical shaft 122. Shaft122 carries a worm 123 adapted to engage a segmental rack 124. Throughrack 124 the tower is tilted -about a horizontal axis provided by shaft89'and trunnion 111 on gear box 105. Rack 124 is rigidly secured to aframe 125 which fits' on one side, are t ereby lessened.

tower mounte When the tower is to be tilted to a position to bore aninclined hole or for ready transportation, lever 79 if not already inposition to cause the en agement of gear wheel 60 and the require gearwheel 59, is moved and then clutch 66 is actuated by operators lever 71.Lever 71 insures that clutch 74, controlling the up and down movement ofthe1 auger, is thrown out of driving position before clutch `66 isthrown into driving position.

Thus if lever 79 is in one position and clutch 66 is thrown' intodriving position, the auger tower and auger is rocked or tilted by theengine through sprocket chain 23, shaft 22, gear wheels 54 and 55, lefthand gear wheel 59, gear wheel 60, shaft 62, clutch 66, gear wheels 64and 115, sprocket wheel 116, sprocket f chain 117, sprocket wheel 118,shaft 119, gear wheels 12() and 121, shaft 1,22, worm 123 and rack 124.

Throwing operators lever 7 9 to the reverse position will move gearwheels 59 so that the right hand gear wheel will engage gear wheel 60.The direction of rotation of shaft 62 will be reversed and the towerwill be tilted in the opposite direction.
